Mixed NO and NC Switching for 230 V AC Control Panels

The Lovato BF26T2A230 combines two normally open contacts and two normally closed contacts in one compact contactor. This mixed configuration allows circuits to be switched in opposite states from the same coil operation, supporting control, changeover-style logic and load switching tasks within industrial electrical panels.

With its 230 V AC 50/60 Hz coil, 45 A AC-1 rating and 26 A AC-3 operating current, the BF26T2A230 is well suited to machine control panels, HVAC systems, automation assemblies and OEM equipment where a compact four-pole contactor with mixed contacts is specified.

Typical Applications

• Industrial control panels requiring two normally open and two normally closed switching poles.
• AC-1 resistive and lightly inductive load switching circuits.
• Motor control circuits requiring 26 A AC-3 contactor performance.
• HVAC, refrigeration and plant control equipment.
• Machine control and OEM electrical assemblies.
• Distribution, isolation and control circuit integration.
• Automation systems using 230 V AC 50/60 Hz control voltage.
