Miniature Circuit Breaker Lockout Device - Pin In Standard (PIS) - 3 Pack

TRADESAFE Pin-in Standard miniature circuit breaker lockout devices provide a compact solution for securing compatible MCB switches during electrical maintenance, repair, inspection, and servicing. This 3-pack features inward-facing pins designed for qualifying single- and multi-pole miniature circuit breakers with compatible openings spaced up to 1/2" apart, distinguishing the PIS configuration from outward-facing Pin Out Standard models.

Each device combines an impact-resistant, nonconductive thermoplastic nylon body with stainless steel pins and a push-button mechanism for tool-free installation. The compact construction is suited to miniature breaker panels where available working space may be limited, while the integrated 9/32" padlock hole allows the installed device to be secured with one compatible personal LOTO padlock.

Miniature Circuit Breaker Lockout for Pin In Standard MCBs

This miniature circuit breaker lockout is designed specifically for compatible breakers that use a Pin In Standard configuration. Its inward-facing pins engage suitable openings in the breaker switch, allowing the lockout to be positioned securely while restricting access to the operating mechanism during servicing.

Part number: TSMCB2. Similar industry part numbers: 90848, S2392

Breaker pole count alone does not determine whether this PIS device will fit. Before ordering, verify that the miniature breaker provides compatible openings for inward-facing pins and that the spacing between those openings does not exceed the stated 1/2" limit.

MCB Lockout Device with Push-Button Installation

This MCB lockout device uses an integrated push-button mechanism to position the inward-facing pins without requiring a screwdriver or another installation tool. Pressing the button allows the device to be aligned with the compatible breaker openings, after which releasing the mechanism seats the lockout so the required personal safety padlock can be attached.

Installation and construction features include:

• Push-button operating mechanism
• Tool-free installation
• Inward-facing pin-in standard configuration
• Stainless steel locking pins
• Impact-resistant nylon housing
• Nonconductive construction
• Compact format for miniature breaker panels
• 9/32" integrated padlock hole
• One compatible LOTO padlock per device
• Designed for repeated electrical maintenance use

The simple push-button format makes these devices practical for recurring electrical servicing where technicians may need to isolate several compatible breakers without carrying separate installation tools. Because three identical lockouts are included, the pack can support multiple isolation points or be divided between electrical maintenance kits, service carts, and work areas.

Miniature Circuit Breaker Lockouts for Electrical Maintenance

These miniature circuit breaker lockouts are designed for electricians, maintenance technicians, contractors, industrial facilities, and commercial workplaces that service compatible MCB panels. Their compact dimensions and Pin-in-Standard configuration make them especially relevant where the breaker provides inward-facing pin openings and a conventional clamp-on lockout would not be the appropriate design.

Before installation, confirm that the breaker matches the PIS configuration and that the relevant hole spacing is no greater than 1/2". Press the button, align the inward-facing pins with the compatible openings, release the mechanism to seat the lockout, and then attach the required personal padlock before beginning maintenance work.

To ensure compatibility, check out our Breaker Lock Solution Guidelines to find the right TRADESAFE Breaker Lockout Device for your specific breaker model and number of poles.

Choose the TRADESAFE 3-pack for compatible Pin In Standard miniature circuit breakers. Verify the breaker opening configuration and spacing before use. Keep these compact MCB lockouts available in electrical maintenance kits so the correct isolation device is ready when servicing begins.
