Motor Switch TeSys GV4 – Reliable Motor Protection

The TeSys GV4 motor switch is a robust and effective solution for protecting electric motors against overload and short circuit. Designed for demanding industrial applications, it ensures safety and reliable operation of electrical installations. Thanks to its compact size and easy installation, it is ideal for both new and upgraded systems.

Characteristics and Applications

This three-pole motor switch, rated at 50A, is designed to protect motors up to 22 kW at 400V and 11 kW at 230V. Its thermomagnetic technology ensures fast and precise response to circuit abnormalities. The use of EverLink terminals simplifies cable connection, providing secure and durable connections. Phase loss sensitivity further enhances operational safety by protecting the motor from damage caused by the loss of one phase.

• Overload Protection: Prevents motor overheating and damage due to prolonged operation above rated current.
• Short-Circuit Protection: Instantly interrupts the circuit in case of a short circuit, minimizing fire risk and equipment damage.
• Phase Loss Sensitivity: Detects the absence of one supply phase and disconnects the circuit, preventing motor damage.
• EverLink Terminals: Enables quick, secure, and hassle-free cable termination.
• Rated Breaking Capacity (Icu): 25 kA at 400V AC – a high value ensuring effective interruption of high-energy short circuits.

The TeSys GV4 switch is suitable for a wide range of industrial applications, including:

• Protection of motors for pumps, fans, conveyor belts, and other mechanical equipment.
• Electrical installations in industrial buildings, workshops, and production halls.
• Industrial automation systems.
• Applications requiring high reliability and operational safety.

Construction and Specifications

The device features a fully enclosed housing, simplifying installation and providing additional protection for internal components. The adjustable thermal trip setting range (20–50A) allows customization of the switch’s characteristics to suit specific application needs. Electronic tripping ensures precise operation, while the rotary knob enables intuitive device handling. The IP40 protection rating guards against access to live parts and ingress of solid objects larger than 1mm. Device dimensions are 81 mm (width) × 155 mm (height) × 165 mm (depth). Power loss is 13.8W at rated operating voltage of 690V AC.
