Miniature Circuit Breaker Lockout Device - Pin Out Wide (POW) - 3 Pack

TRADESAFE Pin Out Wide miniature circuit breaker lockout devices are designed to secure compatible MCB switches during electrical maintenance, inspection, servicing, and repair. This 3-pack uses a wider outward-facing pin configuration for qualifying single- and multi-pole miniature circuit breakers, accommodating compatible breaker openings with spacing up to 11/16".

Each device combines an impact-resistant, nonconductive thermoplastic nylon body with stainless steel pins and a push-button mechanism for quick, tool-free installation. The compact red and black housing is designed for use in miniature breaker panels, while the integrated 9/32" padlock hole allows each installed lockout to be secured with one compatible personal LOTO padlock.

Miniature Circuit Breaker Lockout for Pin Out Wide MCBs

This miniature circuit breaker lockout is specifically designed for compatible breakers that require the wider Pin Out Wide configuration. Its outward-facing pins engage suitable breaker openings with spacing up to 11/16", providing a different fit from standard Pin Out models intended for more closely spaced openings.

Part number: TSMCB4. Similar industry part numbers: 90851, S2391

Product specifications include:

• Quantity: 3 miniature circuit breaker lockout devices
• Pin configuration: Pin Out Wide (POW)
• Outward-facing stainless steel pins
• Compatible hole spacing: up to 11/16"
• Suitable for qualifying single-pole miniature circuit breakers
• Suitable for qualifying multi-pole miniature circuit breakers
• Impact-resistant thermoplastic nylon construction
• Nonconductive body
• Red and black design

• Padlock hole diameter: 9/32"
• One padlock position per device
• Weather-resistant construction
• Chemical-resistant materials
• Tamper-resistant design
• LOTO padlocks sold separately

Compatibility should be confirmed before ordering because miniature breaker designs and pin-hole spacing vary between manufacturers and models. Verify that the breaker provides suitable openings for an outward-facing pin configuration and that the spacing falls within the supported 11/16" limit.

MCB Lockout Device with Push-Button Installation

This MCB lockout device uses an integrated push-button mechanism to position the outward-facing pins without requiring a screwdriver or another hand tool. Pressing the button allows the pins to be aligned with the compatible breaker openings, while releasing the mechanism seats the device so it can then be secured with the required personal safety padlock.

Installation and construction features include:

• Push-button operating mechanism
• Tool-free installation
• Pin Out Wide configuration
• Outward-facing stainless steel pins
• Compatible with hole spacing up to 11/16"
• Impact-resistant nylon housing
• Nonconductive construction
• Compact design for miniature breaker panels
• 9/32" integrated padlock hole
• One compatible LOTO padlock per device
• Designed for repeated electrical maintenance use

The wider pin configuration is the main distinction between this POW model and narrower Pin Out Standard devices. The 3-pack gives maintenance teams multiple identical lockouts for simultaneous breaker isolation or allows the devices to be distributed between electrical kits, maintenance carts, and different work areas.

Miniature Circuit Breaker Lockouts for Electrical Maintenance

These miniature circuit breaker lockouts are suited to electricians, maintenance technicians, contractors, industrial facilities, and commercial workplaces servicing compatible MCB panels. Their small footprint makes them practical for compact electrical equipment, while the wider outward-facing pin arrangement provides a dedicated option for breakers whose opening spacing exceeds the range supported by narrower POS lockouts.

Before installation, confirm that the breaker uses a compatible outward-facing pin arrangement and that the relevant opening spacing does not exceed 11/16". Press the push button, align the pins with the compatible breaker openings, release the mechanism to seat the device, and attach the required personal LOTO padlock before maintenance begins.

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 Out Wide miniature circuit breakers. Verify the breaker opening configuration and spacing before use. Keep these compact POW MCB lockouts available in electrical maintenance kits for fast access when breaker isolation is required.
