Miniature Circuit Breakers deliver supplementary protection.

Press Release Summary:

Rated for 0.5–52 A at 480/277 Vac and 360/180 Vdc, AS168X Series limits let-through energy in event of short circuit up to 10 kA at 277 Vac. Series offers 3 levels of short circuit protection, categorized by F/DF Trip for resistive loads, G/DG for slightly inductive loads, and H/DH Trip for highly inductive loads. Thermal magnetic, positively trip-free breakers, with manual ON/OFF actuation deliver 6,000 cycles. Available from 1–4 poles, DIN rail-mountable units operate from -20 to +60°C.

Original Press Release:

Protect Your Load with AS168X Supplementry Protector for Industrial Applications

Santa Rosa, California, —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.

Various accessories are available for the AS168X series including; a factory mounted switched neutral pole, remote relay/shunt trip module, lockout attachment, as well as, auxiliary and signal contact options.

For the 1-pole AC version, pricing starts at under $25.00 each per 100 pieces. Data sheets and additional information are available at: . For sales and product information, contact Cora Umlauf at (800) 848-2600 or by email at
