Nonfuse actuators connect in parallel with 50A or higher fuses to provide a visual indicator that makes it easier to identify blown fuses for replacement. They fit into a matching spring-loaded fuse holder or signal block that will eject the actuator when the circuit opens. They're commonly used with shunt-tip fused switches in industrial and commercial electrical installations.

DIN rail adapters are brackets that attach to a fuse block so it can be snapped onto a DIN rail for mounting. They're commonly used for mounting fuse blocks to an electrical panel or box.

Auxiliary contacts mount to a compact circuit protector (CCP) and send a signal to monitoring or control equipment when the CCP has opened a circuit. These contacts can be manually reset after resetting the CCP. They include hardware for mounting.

Type D fuse cap gauges are rejection inserts that prevent fuses with an incorrect rating from being installed in a fuse block. They're used with Type D diazed fuses that are typically found in European-manufactured equipment. These fuse cap gauges fit into a screw-cap link carrier and install into a Type D fuse block.
