Supplementary Protectors

Offering maximum reliability and accuracy, the Supplementary Protectors fit various applications (of which there are many) where a fuse may have been previously used. The advantage over fuses is that it is resettable and the device’s status is easily and clearly identified by the position of the handle and the flag indicator. With easy mounting of the device on a 35 mm DIN rail and also the "Quick 3 Step" field mountable accessories, it is now easier for the customer to select and apply this modular range. Due to the smaller modular width of the device and accessories, it enables them to save space in their panel or equipment - which directly leads to cost savings.
 
Supplementary Protectors are ideal for providing protection in a multitude of applications, including:
 
• Motor Control Circuits
• Control Power Transformers
• Relays
• Contactor Coils
• PLC I/O points
• Lighting Circuits

The SPHM Supplementary Protector is a dual rated product for both AC and DC supplies, in accordance with UL 1077, CSA 22.2 No. 235, VDE 0660 and IEC 60947-2 standards.

Eaton’s WMZS line of miniature circuit breakers includes a broad range of devices defined as “supplementary protectors.
