Honeywell Commercial MS4104F1210 Damper Actuator

The Honeywell Commercial MS4104F1210 Damper Actuator delivers precise 2-position control with fast acting SPST operation. This direct-coupled, spring-return actuator runs on 120 Volt AC (60 Hz) and provides 18 W driving power and 9 W holding power, with a driving current of 0.18 A and holding current of 0.11 A. It offers 30 in-lb torque across a 95° rotation for reliable damper positioning in fire and smoke applications. The unit features a sturdy aluminum body in a NEMA 1/IP40 enclosure, engineered for durability in commercial environments. Its 15-second timing ensures quick damper response, while the 1/2 inch shaft and compact dimensions (5.13" W x 3.32" D x 8.9" H) simplify mounting. UL 873, CUL C22.2, and C-Tick approvals confirm safety and compliance for regulated installations, and the design includes two auxiliary switches for expanded control and signaling needs.
