TeSys GV4 motor-protective circuit breaker, 3-pole, 80A, Icu=25kA, toggle, Everlink terminals GV4P80B

Motor starter switch – reliable protection for your installation

This three-pole TeSys GV4 motor starter switch is a robust solution for protecting electric motors and circuits against overload and short circuit. A rated continuous current of 80A and a high short-circuit breaking capacity of 25kA guarantee effective protection even in demanding working conditions. The design with a lever and Everlink terminals ensures convenient installation and secure connections.

Characteristics and application

The GV4P80B switch is designed to operate in installations with a rated voltage of 690V AC. The adjustable overload release range (40-80A) allows for precise matching to the load characteristics. Built-in thermal protection and phase failure sensitivity further increase safety and reliability. This makes the switch suitable for both industrial applications and commercial buildings where high interference resistance and stable operation are required.

Key features and benefits

• High short-circuit breaking capacity (Icu=25kA): ensures quick and safe disconnection of the circuit in the event of a short circuit, minimizing the risk of equipment damage and hazards to people.
• Thermal protection: protects the motor from overheating caused by overload, extending its service life.
• Phase failure sensitivity: detects the absence of one of the supply phases, which prevents damage to the motor operating under such conditions.
• Adjustable overload setting range (40-80A): allows you to match the switch to the specific load, ensuring optimal protection.
• Solid construction (IP40): provides resistance to dust and moisture, enabling operation in harsh environmental conditions.
• Everlink terminals: guarantee quick, secure and reliable cable connection.
• Dimensions: 81 mm width, 155 mm height and 165 mm depth allow for easy integration with existing installations.
• Motor power: The rated operating power for AC-3 is 37 kW at 400 V and 22 kW at 230 V, making it suitable for a wide range of applications.
• Power loss: Low power loss (13.8 W) translates into energy savings during device operation.
