Mains inlets with resettable circuit breaker

10 September 2003 Circuit & System Protection Perimeter Security, Alarms & Intruder Detection

The latest addition to Bulgin's Polysnap range of mains inlet modules now incorporates a miniature circuit breaker. Polysnap modules have previously used conventional fused inlets but this circuit breaker version now provides an alternative where resettable circuit protection is required. Two styles are available, one with IEC60320 C14 or C16 (hot condition) inlets and one with C20 inlets.

The C14/C16 versions snap-fit into a rectangular panel cut out measuring 34 x 40 mm. Stepped fixings suit 1, 1,5, 2 and 3 mm thickness panels. The circuit breakers are available with 5, 8, 10 or 15 A trip currents and have a typical trip speed of 0,3 - 1,8 secs with a 600% overload at 25°C.

The higher current C20 version fits a 34 x 56 mm panel cut out and the circuit breaker can be specified with 5, 8, 10, 15, 16 or 20 A trip currents.

Rocker options include red and green illumination with 125 or 250 V neons and non-illuminated types both with RESET and OFF legends. These circuit breaker and mains inlets carry UL and CSA approvals.

These additions further extend Polysnap's range, offering a very adaptable and flexible solution to panel design. With over 26 000 combinations, the compact design of Bulgin's Polysnap occupies just the minimum of panel area with a single rectangular mounting hole offering easy installation.
