Overview
The IDEC 858T FB control box is a Type 4X IP65 rated pushbutton switch engineered for industrial control station applications. Designed for indoor use with screw termination, this unit combines robust protection with straightforward electrical integration. It operates using an on/off method and is suitable for both AC and DC current types, making it adaptable to a wide range of control circuits and machinery.
Key Features
- Type 4X IP65 Rating: IP65 protection is achieved when appropriate nameplates are used, providing comprehensive dust and moisture resistance for harsh industrial environments
- Retractive Pushbutton Style: Self-returning button design for momentary control applications
- Dual Voltage Support: Operates on both AC and DC current types, eliminating the need for separate AC/DC variants
- Screw Terminal Connections: Reliable, field-serviceable electrical termination without requiring specialized tooling
- Multiple Button Colors: Available in red, green, orange, or black button colors for color-coded control logic
- Two-Position Configuration: Single switching action with 2-position operator design

Compatibility & Replacements
The IDEC 858T FB is part of IDEC’s established HW series control station ecosystem. This unit integrates with standard industrial control architectures and pairs with compatible contact blocks and switching configurations. For systems currently using IDEC Type 4X control boxes, the 858T FB serves as a direct replacement provided button color and terminal type match application requirements. Used units should be inspected for button responsiveness and electrical continuity prior to installation. Verify voltage rating and contact configuration compatibility with your existing control circuit before substitution.
