PRODUCT DESCRIPTION
ASEA BROWN BOVERI CI547 - Contactor Interlock Unit
The ABB CI547 is a dedicated mechanical interlock unit engineered to prevent the simultaneous closure of two contactors in motor control and power switching applications. This component ensures operational safety and system integrity by providing a robust mechanical barrier, critical for reversing starters, automatic transfer switches, and other interlocking circuits. It integrates seamlessly with specified contactor series, facilitating reliable and compliant industrial control system design.
Technical Specifications:
- SERIES/FAMILY: CI Series (Contactor Interlock)
- COMPONENT TYPE: Mechanical Contactor Interlock Unit
- ELECTRICAL SPECS: Not applicable to the interlock unit itself designed for use with contactors rated up to 690VAC / 1000VDC and various operational currents.
- MECHANICAL/PHYSICAL: Front-mounted between two contactors provides mechanical interlocking action constructed from durable engineering plastics and metal components.
- INTERFACE/CONTROL: Purely mechanical interlocking mechanism no electrical connections or control signals are processed by this unit.
- ENVIRONMENTAL/MOUNTING: IP RATING: IP20 (typical for enclosed panel components) MOUNTING STYLE: Tool-less, snap-on installation between compatible contactors.
- COMPATIBILITY/APPLICATION: Specifically designed for use with ABB AF09 to AF38 contactors and A9 to A40 contactors essential for reversing motor starters, dual-source transfer systems, and safety-critical interlocking circuits.
