this is the industry-standard equivalent to the MARS 90342 and can be used interchangeably in most furnace and air conditioning applications

Its snap-action bimetal disc design provides responsive switching

supporting multiple mounting configurations for faster service calls

Field technicians rely on its modular design and robust relay construction for consistent staging control in harsh HVACR environments

Field performance depends on the integrity of the regulator spring to counteract the diaphragm assembly

Belimo K7-2 Standard Clamp this is the industry-standard equivalentWhen you are outfitting Belimo AFB or NFB series actuators, the Belimo K7 2 Standard Clamp is the essential mechanical interface for direct coupled damper shaft mounting. This reversible, galvanized steel clamp is engineered for high torque applications, providing a slip free grip on damper shafts with diameters of 1 2", 3 4", or 1. 05". Its symmetrical design allows for versatile central mounting, ensuring the actuator remains perfectly perpendicular
