Miniature Circuit Breaker for Industrial Applications

SCHURTER's AS168X thermal magnetic, high performance miniature circuit breaker is UL 1077 approved. The units are available in either ac or dc with the same frame size for industrial applications such as HVAC systems, commercial ovens, industrial printers, industrial converters and inverters.

The family has three levels of short circuit protection, categorized by F/DF Trip for resistive loads, G/DG Trip for slightly inductive loads and H/DH Trip for highly inductive loads. Rated for 0.5 to 52 A @ 480/277 VAC and 360/180 VDC, the high performance CBE limits let-through-energy in the event of a short circuit up to 10 kA at 277 VAC. The units are available from 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) and is operational with an ambient temperature range of -20°C to +60°C.

SCHURTER's AS168X series is DIN Rail mountable, style EN50022, for quick installation. Screw terminal connections at line and load accept a range of wire sizes 16 - 4 AWG; compact in design, measuring 17.5 mm in width, these circuit breakers conserve panel space and are well-suited for high-density configurations. They have ingress protection of IP40 from the front side is in accordance with IEC 60529. The circuit breaker is RoHS compliant.
