Magnetic Differential 10A Screw Connection

The Schneider Electric TeSys Deca GV2L14 is a 3-pole 10 A motor circuit breaker or magnetic circuit breaker, designed to protect motors against short circuits. It features an exclusively magnetic trip unit, rotary handle, and screw connection terminals, offering a compact solution for motor control panels, automation, machinery, and industrial installations.

The GV2L14 reference belongs to the TeSys GV2 range and provides a high breaking capacity, reaching 100 kA Icu at 400/415 V AC. As it provides only magnetic protection, it does not include thermal overload protection, so it must be paired with a suitable thermal overload relay when the application requires complete motor protection.

Magnetic protection for motors

The GV2L14 uses a magnetic trip unit designed to act quickly when a high current caused by a short circuit occurs. This technology makes it possible to interrupt the circuit before the fault current can cause significant damage to conductors, contactors, or motors.

• Protection type: magnetic.
• Rated current: 10 A.
• Magnetic trip current: 149 A in the manufacturer's current specification.
• Number of poles: 3P.
• Application: motor protection.

It is important to distinguish this product from a conventional thermal-magnetic motor circuit breaker. The GV2L14 does not include an adjustable thermal trip unit to protect the motor against prolonged overloads.

High breaking capacity up to 100 kA

One of the main features of the Schneider Electric GV2L14 is its high short-circuit interruption capacity. The breaking capacity depends on the operating voltage:

• 230/240 V AC: 100 kA Icu.
• 400/415 V AC: 100 kA Icu.
• 440 V AC: 20 kA Icu.
• 500 V AC: 10 kA Icu.
• 690 V AC: 4 kA Icu.

The service breaking capacity Ics reaches 100% of Icu at 230/240 V, 400/415 V, 500 V, and 690 V, while at 440 V it is 75%.

For three-phase motors

The GV2L14 is designed for motor applications in AC networks and complies with utilization categories AC-3 and AC-3e according to IEC 60947-4-1.

Schneider Electric places this reference within applications for three-phase motors of approximately 3 to 4 kW at 400/415 V, depending on the motor's characteristics and operating conditions.

• Motor power at 400/415 V: up to 4 kW depending on application.
• Power at 500 V: up to 4 kW.
• Power at 690 V: up to 7.5 kW depending on configuration.

The final selection must be made taking into account the rated current, power, voltage, starting characteristics, and thermal protection required by the motor.

Up to 690 V AC

The circuit breaker supports a rated operational voltage of up to 690 V AC at 50/60 Hz. It also has a rated insulation voltage of 690 V and an impulse withstand voltage of 6 kV.

• Rated operational voltage Ue: up to 690 V AC.
• Frequency: 50/60 Hz.
• Insulation voltage Ui: 690 V.
• Impulse withstand voltage Uimp: 6 kV.
• Conventional free-air thermal current Ith: 14 A.

Rotary handle operation

The TeSys GV2L14 incorporates a rotary handle that allows manual start and stop operations. This system makes it easy to use the device as a control element inside the electrical panel.

The product is also suitable for isolation according to IEC 60947-1, allowing the circuit to be isolated within the conditions established by Schneider Electric.

No integrated thermal protection

The GV2L14 provides magnetic protection against short circuits, but it does not on its own protect the motor against thermal overloads. To obtain complete protection, it must be combined with a suitable overload protection device.

Schneider Electric includes, among other compatible combinations, the use of a TeSys Deca LRD14 thermal overload relay, selected according to the motor's rated current.

This configuration makes it possible to separate instantaneous short-circuit protection from thermal overload protection, which is common in motor starters made up of a magnetic motor circuit breaker, contactor, and thermal overload relay.

DIN rail or plate mounting

The Schneider Electric GV2L14 offers installation flexibility and can be mounted directly on a 35 mm symmetrical DIN rail or screwed onto a mounting plate.

• DIN rail mounting: via clip.
• Plate mounting: using 2 M4 screws.
• Mounting position: horizontal or vertical.

Its width of only 45 mm makes it possible to build compact motor starters together with contactors, thermal overload relays, and TeSys range accessories.

Screw terminal connection

The GV2L14 reference uses screw terminals for the power circuit, providing a robust conductor connection.

• Rigid conductors: up to 2 x 6 mm².
• Flexible conductors without ferrule: up to 2 x 6 mm².
• Flexible conductors with ferrule: up to 2 x 4 mm².
• Tightening torque: 1.7 Nm.

100,000-cycle durability

The motor circuit breaker is designed to withstand a high number of operations. Schneider Electric declares a mechanical durability of 100,000 cycles and an electrical durability of up to 100,000 cycles in AC-3/AC-3e applications at 415 V within its rated conditions.

• Mechanical durability: 100,000 cycles.
• Electrical durability AC-3: 100,000 cycles.
• Electrical durability AC-3e: 100,000 cycles.
• Rated service: continuous.

Compact 45 mm format

The compact design of the TeSys GV2 range makes it possible to integrate motor protection in panels with limited space.

• Width: 45 mm.
• Height: 89 mm.
• Depth: 97 mm.
• Net weight: approximately 0.33 kg.

Compact magnetic protection for motors

The Schneider Electric TeSys Deca GV2L14 is a solution especially suited for protecting motors against short circuits in automation panels and starters. Its combination of 10 A, 3 poles, breaking capacity up to 100 kA at 400/415 V, rotary handle, and 45 mm width makes it easy to build compact, high-performance motor control systems.

To also provide overload protection, it must be complemented with a properly sized thermal overload relay. In this way, the GV2L14 can be integrated with TeSys contactors and relays to create complete motor control and protection solutions.
