Purchase now the 194R-PLA1, a critical safety and operational accessory for the Allen-Bradley Bulletin 194R fused disconnect switch line. This side-mount lever and terminal cover assembly are engineered to provide enhanced operator protection and secure mechanical actuation in heavy-duty industrial control panels.
What Is the 194R-PLA1?
The 194R-PLA1 is a specialized hardware accessory designed for the 194R series of rotary disconnect switches. It serves two primary functions: providing a robust mechanical lever interface for side-mounted operation and acting as a protective barrier (terminal cover) for the electrical connections. This component is essential for meeting IP20 finger-safe requirements within an enclosure. It is specifically designed to work with non-fusible and fusible disconnect switches rated up to 30A or 60A depending on the specific frame size. The 194R-PLA1 is built from high-impact thermoplastic, ensuring it can withstand the mechanical stresses of high-cycle industrial environments without compromising the electrical isolation of the disconnect switch assembly.

Industrial Architecture and Safety
Integrating the 194R-PLA1 into your panel architecture ensures compliance with strict safety standards regarding exposed live parts. When used in a side-mount configuration, it allows for a more compact panel layout by moving the actuation point away from the main DIN rail space. This is particularly useful in narrow enclosures or where top-of-unit access is restricted. The 194R-PLA1 ensures that even when the enclosure door is open, maintenance personnel are protected from accidental contact with line-side terminals, a key requirement for NFPA 70E compliance.
Expert Tips
When installing the 194R-PLA1, ensure that the mechanical linkage between the lever and the switch body is perfectly aligned before tightening the mounting screws. If the lever feels unusually stiff, do not force it; misalignment can lead to internal mechanical wear or a failure to fully engage the contacts. For maximum safety, always verify that the cover is snapped securely into place, as it also serves as a visual indicator that the terminal section is properly enclosed.
Frequently Asked Questions
Q: Can the 194R-PLA1 be used on both fused and non-fused 194R switches?
A: Yes, the 194R-PLA1 is designed to be compatible with both versions, provided they fall within the supported frame size (typically 30A to 60A).
Q: Does this kit include the actual disconnect switch?
A: No, the 194R-PLA1 is an accessory kit. The disconnect switch body must be purchased separately based on your required current and voltage ratings.
