1. GPTCRM01 Substitution Conclusion The GPTCRM01 demonstrates fundamental substitution compatibility with the original BZ-2RM22-A2 model in key electrical parameters (SPDT, 15A 125V AC) and mounting method (screw terminals). Key differences include: first, the actuator type is changed from a straight lever to a roller lever, which may affect mechanical compatibility and actuation angle; second, the operating force (158gf) and release force (43gf) are significantly lower than those of the original model (538gf/170gf), resulting in a lighter tactile feel and easier operation, but potentially increasing susceptibility to accidental actuation in high-vibration or high-shock environments; third, millimeter-level differences in travel parameters (pre-travel, differential travel, etc.) may impact actuation accuracy and installation adjustment. If the application does not impose strict requirements on operating force, actuator shape, or travel, and is intended for AC loads only, the GPTCRM01 can serve as a substitute, though mechanical fit and environmental reliability should be validated.
