SCHURTER’s AS168X thermal magnetic, high performance circuit breaker is a UL 508 listed, manual motor controller. The AS168X provides motor disconnect from 0.5A to 30A, and motor protection from 10Hp to 20Hp for industrial control applications.

The AS168X series is rated 0.5A to 52A at 480Y/277VAC. The high performance CBE limits let-through energy in the event of a short circuit up to 10kA at 277VAC. The family has three levels of short circuit protection, categorized by F, G and H curves and is available in one to four poles. Multi-pole devices are connected internally and at the handle for simultaneous operation. This applies also to combinations with the switched neutral pole. The thermal magnetic, positively trip free breaker, with manual ON/OFF actuation has a high endurance (life cycle) of 6000 cycles (In) with an ambient temperature range of -20°C to +60°C.

This thermal magnetic circuit breaker combines a latching type bimetal with a magnetic coil to ensure protection and genuine physical contact isolation. This provides the joint benefits of delayed operation for low level over-current protection and fast magnetic action of higher value short circuits, disconnecting the faulty, circuit within milliseconds. The AS168X starts stops, regulates, controls and protects 1 and 3-phase electric motors.

SCHURTER’s manual motor controller is DIN rail mountable, style EN50022, for quick installation. Screw terminal connections at line and load accept a range of wire sizes 16 – 4AWG; compact in design, measuring 17.5mm in width, these circuit breakers conserve panel space and are well-suited for high-density configurations. Ingress protection of IP40 from the front side is in accordance with IEC 60529.
