Fuses

The Edison JHL Series of 600VAC/450VDC Class J fuses combines the performance of high-speed semiconductor fuses and the convenience of Class J branch-circuit fuses in one small package, providing protection for AC and DC drives and controllers. Suitable for use with power semiconductor devices that use diodes, GTOs, SCRs, or SSRs, as well as electronic motor controllers, the fuses are available in 1A to 600A sizes. In addition, the devices are current limiting and are designed with no intentional time delay to open quickly on overload.

Overload Relays

Sirius 3RB24 electronic overload relays now feature IO-Link communication technology. According to the company, IO-Link represents an open, standardized, and manufacturer-independent system for the uniform connection of sensors and switching devices to the control level. Contactors that are connected to the overload relays provide integrated motor protection and communication advantages, including readout of motor current and diagnostics. Rotary switches allow for easy setting of the device’s motor current and the required trip class.
