ABB ESB100-40N-06 inštalačný stýkač 4S/0OE, 230 V AC/DC, 4 NO, 100 A 1SAE661111R0640

Switching heavy single-phase or multi-phase loads in residential and commercial installations often requires a contactor that can handle high currents while being easy to mount and wire. The ABB ESB100-40N-06 installation contactor provides four normally open main contacts, a wide coil voltage range, and DIN rail mounting to simplify control of lighting, heating, and motor circuits.

Who is it for

Electricians, panel builders, and facility managers who need a reliable, compact contactor for switching loads up to 100 A in AC-1 duty. It suits distribution boards, control cabinets, and building automation systems where space is limited and performance must be consistent.

Main features

• 4 main contacts, all normally open (4 NO), for switching up to 4 separate circuits or combining poles for higher current.
• Coil voltage 230 V AC/DC, allowing operation from both AC and DC control signals without changing the coil.
• Rated operational current 100 A in AC-1 and AC-7a categories at 400 V, 55 °C; 30 A in AC-7b for motor loads.
• Rated insulation voltage 500 V and impulse withstand voltage 4 kV for safe isolation in standard installations.
• DIN rail mounting (35 mm) for quick installation and removal.
• Screw terminals for secure, maintenance-friendly connections.
• Mechanical durability of 1,000,000 cycles and electrical durability of 150,000 cycles for long service life.
• Compact design with IP20 protection, suitable for installation in enclosed boards.

Tips

Ensure the control circuit can supply the coil inrush current, especially when several contactors are switched simultaneously. For motor loads, verify the AC-7b rating matches the motor's full-load current. Mount in a ventilated enclosure to maintain ambient temperature within limits.
