General Electric Company TEY320ST6 Circuit Breaker

The GE TEY320ST6 circuit breaker is a three-pole, 20-amp protective device built to interrupt power in three-phase circuits. It includes a TEYST6 shunt-trip accessory that provides remote tripping capability, enabling an external signal to initiate a shutdown for safety or process control. With a voltage rating of 480/277 V, it is suitable for use in industrial and commercial power-distribution applications that operate on high-voltage three-phase systems. The combination of a 20-amp rating and remote-trip option supports fast isolation of the protected circuit while maintaining a structured protection scheme in electrical panels and distribution boards. In routine operation, it helps ensure that any fault current is quickly interrupted to protect downstream equipment, reduce downtime, and maintain system integrity. The TEYST6 shunt-trip can be wired to control circuits or protective relays to coordinate with other safety systems, offering flexible integration in complex electrical installations.
