Resideo Braukmann 220736b Internal Auxiliary Switch Assembly 2 Switches

Product Description

The Resideo Braukmann 220736b is an Internal Auxiliary Switch Assembly designed for use with TRADELINE Modutrol IV Motors. This kit includes two Micro Switch V3 precision switches that are actuated by adjustable cams located inside the motor. HVAC technicians and building automation professionals use this assembly to add auxiliary switching capability to Modutrol IV motor-driven actuators, enabling better control sequencing and system integration. Each switch operates as an SPDT On/Off switch, making it suitable for a wide range of control signal applications in commercial and industrial HVAC systems. The 220736b is a reliable internal auxiliary switch kit that supports both 120 Vac and 240 Vac circuits, giving technicians flexibility when wiring into existing or new control panels. The assembly is rated at 7.2A AFL at 120 Vac and 3.6A AFL at 240 Vac, with locked rotor ratings of 43.2A ALR at 120 Vac and 21.6A ALR at 240 Vac. These ratings make it capable of handling the inductive loads common in HVAC motor control applications. Power consumption for driving the assembly is 20 VA, which is well within the capacity of standard Modutrol IV motor systems. Lead wires measure 15 inches in length, providing enough reach for clean, organized connections inside a motor housing or control enclosure. The ambient temperature range runs from 0 degrees Fahrenheit to 131 degrees Fahrenheit, or -18 degrees Celsius to 55 degrees Celsius, covering the full range of typical mechanical room and rooftop unit environments. This switch kit is a direct replacement or upgrade option for Modutrol IV motor auxiliary switch applications, and it is commonly used by HVAC controls technicians for zone valve actuators, damper actuators, and other motorized control devices where position feedback or interlocked switching is required.
