Compatibility & Replacements
The 100-F Series B contact block is a direct fit for existing 100-C contactor installations. Interchangeable with earlier Series A versions where mechanical compatibility is confirmed. This lot of 4 units provides spare capacity for multi-contactor control systems, reducing downtime from contact wear or failure. For systems requiring side-mount configuration, the parallel 100-S Series B contact block offers identical electrical specifications with alternative mounting. Always verify mechanical mounting geometry with your specific contactor generation before ordering replacement stock.
