Overview
The Allen-Bradley 800T-H31 is a 30.5mm heavy-duty selector switch designed for demanding industrial automation environments. This non-illuminated selector switch features a maintained action with a cylinder lock allowing key removal on the left side. It is rated for NEMA 4/13 environments, suitable for harsh industrial conditions. Supplied without contact blocks, this switch accepts standard contact modules for flexible circuit configuration.
Key Features
- Maintained action with cylinder lock — operator can lock the switch in either position
- Key removal from left, Key Code D018, Operator Only — secure operation with standardized D018 key
- Supports wire sizes from 18 to 14 AWG with screw terminal connection
- Accepts standard 1 NO / 1 NC contact block configuration for flexible control circuit design
- Non-illuminated black knob actuator for clear two-position indication
- 30.5mm flush panel mounting with low profile enclosure fit
Technical Specifications
The 800T-H31 conforms to recognized industrial control standards and integrates seamlessly into existing automation panels.
Typical Applications
- Machine startup/shutdown control in NEMA 4/13 cabinets
- Process mode selection (Run/Stop, Forward/Reverse)
- Operator-controlled circuit isolation in food, chemical, and pharmaceutical environments
- Washdown and corrosive atmosphere applications requiring sealed enclosures
- OEM panel builder standardization across multiple equipment platforms
Compatibility & Replacements
The 800T-H31 is the base selector unit without pre-installed contacts. The 800T-H31A variant includes factory-assembled 1 NO/1 NC contact blocks and is a direct replacement for many applications. Both models use the same 30.5mm panel cutout. Standard D018 key is supplied with cylinder lock models. Retrofit applications should verify contact configuration requirements before ordering contact modules. Allen-Bradley selector switches in the 800T series maintain consistent pin spacing and terminal arrangements for reliable cross-model compatibility.
