Control Circuit Protection

Siemens circuit protection devices are engineered to allow for easy deployment, quick installation and secure protection of industrial devices from excessive current flow. Siemens low voltage circuit protection devices such as, miniature circuit breakers, supplementary protectors and fuse holders, range in performance and style to meet wide-ranging needs.

Miniature Circuit Breakers are 1-, 2- and 3-pole thermal/ magnetic overcurrent protection devices that are intended for general industrial use such as Branch Circuit Protection. Suitable for applications up to 277 VAC and 60 VDC (1-pole); and, up to 480Y VAC and 125 VDC (2- and 3-pole).

All fuse holders are equipped with either a fuse handle or draw mechanism for easy insertion and removal of cylindrical type fuses. During insertion and removal the fuses are isolated from the power/control circuit. Their compact size requires less space than typical open-type fuse holders and they mount directly onto standard 35 mm mounting rails.

Siemens' UL 1077 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device.  Since our Supplementary protectors are made to trip faster than a standard UL 489 Circuit Breaker they provide additional protection for more sensitive devices inside the panel.

As the key termination point to every control panel, Siemens terminal blocks provides an extensive variety of connection types, colors, sizes and ratings in order to allow for the quick connection of incoming and outgoing conductors in a control system. Siemens terminal blocks are to be used domestically; and, incorporated into equipment which will be exported.
