100-A30ND3 Ser B (PU)

Allen Bradley Bulletin 1352 | Catalog 100 30A Contactor Unit (CTU)

Contactor Unit (CTU) 3 Pole 1 N.O. Coil: 120Vac 60Hz, 30Amp. 730Kva Series B Listed: UL/CSA

The Allen-Bradley 100-A30ND3 is a 3-pole, 30 Amp AC contactor from the Bulletin 100-A IEC contactor series, featuring a 120V AC coil and DIN rail mounting. Rated at 20 HP, it is designed for general-purpose motor control and load switching in industrial automation applications.

The Bulletin 100-A series is Allen-Bradley's legacy IEC contactor platform, built to IEC 947 / BS 5424 / VDE 0660 standards. The contactor carries an insulation voltage (Ui) of 690V and a thermal current rating (Ith) of 22A AC1, making it suitable for resistive and slightly inductive load switching in addition to motor starting duty. The catalog number suffix "ND3" indicates three normally open (N.O.) main power poles with a 120V AC coil operating at 110V/50Hz or 120V/60Hz.

The contactor accepts direct-mount overload relays from the 193-series and 592-series to form a complete IEC motor starter assembly, and is compatible with a range of add-on auxiliary contact blocks for enhanced control circuit flexibility. The 3-pole configuration makes it well suited for three-phase motor control applications including conveyors, pumps, fans, compressors, and other general industrial machinery.

The 100-A30ND3 Series B is rated for up to 600VAC and 30A maximum, and supports both non-reversing and reversing contactor configurations.
