KKM Solutions is an independent parts distributor, not an authorized Johnson Controls dealer — how we source.
Overview
Part number A25CN-4C from Johnson Controls, listed in Control Relays. KKM Solutions quotes this part with pricing and availability confirmed per order.
Overview The Johnson Controls A25CN-4C is an electromechanical warm air limit control designed to automatically shut down systems like fans, burners, and dampers when the sensed air temperature exceeds the user-defined setpoint. It features a visible adjustment knob and utilizes a rigid bi-metal rod and tube sensing mechanism. Designed for applications requiring high-limit safety enforcement, the device features a positive, trip-free manual reset mechanism that locks out the electrical circuit until manual intervention occurs after temperatures cool. Features Manual Reset: Enforces safety lockout when temperature limits are breached, requiring manual resetting once the temperature drops 20°F (11°C) below the setpoint. SPDT Switching: Equipped with Single Pole Double Throw contacts, providing versatile wiring configurations for controlling safety loops and indicator systems. Robust Sensing: Employs a reliable bi-metal rod and tube design engineered for industrial duct environments. High Visibility: Features an external, highly visible setpoint knob for straightforward checking and local adjustment. Specifications Temperature Range: -4°C to 101°C (25°F to 215°F) Relay/Switch Type: Snap-acting SPDT contacts in a dust-protected enclosure High Limit Dial Stop: 125°F (52°C) Sensing Element: Bi-metal rod and tube construction Enclosure Materials: 0.063-inch galvanized steel case with a 0.025-inch cold-rolled steel cover finished in gray baked enamel Electrical Ratings: 16 FLA / 96 LRA at 120 VAC; 9.2 FLA / 55.2 LRA at 208 VAC; 8 FLA / 48 LRA at 240 VAC; 16 A non-inductive; Pilot Duty 125 VA at 24 to 600 VAC Approvals: UL Listed, cUL Listed Applications High-Limit Safety: Ideal for installation in supply air ducts or plenums to prevent dangerous overheating situations.
