Bolt On Miniature Circuit Breakers

Square D EDB Series lighting panelboard circuit breakers are designed to distribute an electric power feed into branch circuits, thereby protecting from short circuits or overload conditions. These units feature a bolt-on mechanism (NF panelboards) for handling vibrational loads and a lug-type terminal configuration allowing straight-in wiring facility and the elimination of pigtail wires. They further come equipped with a Visi-trip indicator to display the status of the interrupted circuit in the system and are available in 70 and 125 A frame sizes. Choose from a wide range of these breakers available in ground fault equipment protection (EPD), shunt trip (SA) and standard type variants on Raptor Supplies.

Siemens HED Series bolt-on circuit breakers are used in commercial buildings, industrial facilities and data centres to protect circuits from overcurrent conditions. They are widely installed in lighting outlets, electronic appliances, HVAC systems, heavy machinery or motors. They have a bolt-on connection and a thermal-magnetic trip that provides both instantaneous and time-delayed protection. These ED circuit breakers feature a three-phase three-pole configuration for balanced current distribution and efficient fault detection. They can be reverse-connected as per the user's requirement.
