The IKA25-40/4NO is a 2-module DIN rail contactor from Iskra, operating on a 230V AC excitation voltage at 50/60 Hz. Its four normally open (NO) contacts and 25A thermal current rating make it the preferred choice for switching three-phase circuits — lighting, heating, and motor applications — in offices, shops, hospitals, sports facilities, and production halls.

The 60mm built-in depth fits standard distribution boards, and the 400V rated operating voltage supports both three-phase and single-phase networks. The 2-module width accommodates the additional two poles while remaining DIN rail compatible.

Key Features

• 4-pole (4p), 2-module DIN rail format — four switched poles in a compact package
• 4 × normally open (NO) contacts for three-phase circuit switching
• 230V AC excitation voltage, 50/60 Hz — standard mains-compatible coil
• Rated operating current AC-1: 25A; thermal current Ie: 25A
• Rated operating voltage: 400V

Product Benefits

• Four-pole switching enables simultaneous control of all three phases plus neutral
