Contact Block 2NO 16 mm
This Schneider Electric ZB6Z3B contact block provides two normally open contacts for industrial control circuits. It is designed for use with Schneider 16 mm push button operators in automation panels and machine interfaces.
Contact rating 6 A at 250 V AC
The single specification that determines fit is the 6 A, 250 V AC rating with NEMA B300/R300 designation. Circuits exceeding this current or voltage require a different contact block.
Standards and terminal headroom
The block meets IEC 60947-1, IEC 60947-5-1, IEC 60947-5-5, JIS C4520, JIS C852, CSA C22.2 No. 14 and UL 508. Slip-on or Faston quick connectors speed wiring, but the 6 A limit means it cannot handle heavier motor loads or higher-voltage control circuits.
