Overview
The Allen-Bradley 100-C16ZJ01 Series B is a general-purpose industrial contactor designed for motor control and switching applications across manufacturing, HVAC, and facility maintenance environments. This 24VDC contactor combines IEC standardization with proven Rockwell Automation reliability, making it a preferred replacement for aging or discontinued contactors in legacy equipment. The unit features three main power poles, 1 normally closed (N.C.) auxiliary contact, and screw-type line terminals for straightforward panel integration.
Key Features
- Three-pole configuration: 3 N.O. (normally open) main contacts for balanced three-phase motor control
- 16A rated current: Handles small to mid-range industrial motors and loads across multiple voltage classes
- 24VDC coil: Standard industrial control voltage; compatible with most legacy PLC, relay, and automation control systems
- 1 N.C. auxiliary contact: Enables interlocking, status indication, and safety feedback logic without additional hardware
- IEC standardized design: Direct mechanical interchangeability with other 100-C series contactors and accessories
- Screw terminal connections: Field-proven connection method; no crimped terminals reduce maintenance failures
Technical Specifications
Power ratings span from 5 HP at 200/230V to 15 HP at 575V three-phase. The coil draws nominal current at 24VDC, with standard industrial duty cycle ratings. Operating temperature ranges from 0–55°C ambient; storage rated to -20–70°C. The unit measures approximately 71 mm wide by 75 mm deep by 140 mm high with a net weight under 0.5 kg, enabling compact DIN rail or base mounting. Certifications include UL, CSA, and CE compliance for North American and European installations.
Typical Applications
- Three-phase motor soft-start and emergency stop circuits in manufacturing facilities
- HVAC compressor and pump motor control systems
- Legacy facility automation systems requiring drop-in replacement contactors
- Interlock and safety feedback logic in machine guard and process control cabinets
- OEM equipment upgrades where 16A IEC contactors are specified
Compatibility & Replacements
The 100-C16ZJ01/B is part of Rockwell’s 100-C Bulletin series. It integrates directly with standard 100-C auxiliary contact blocks, 100-S overload relays, and 100-F contactor enclosure frames. Technicians and system integrators commonly use this part to replace or upgrade equivalent 16A IEC contactors from competing manufacturers. When sourcing replacements, confirm coil voltage (24VDC), pole configuration (3-pole), and auxiliary contact count (1 N.C.) to ensure seamless integration. The Series B variant reflects post-2021 manufacturing updates and is fully compatible with earlier and later 100-C modules.
