Cooper Bussmann BP/S-6-1/4 Type S Plug Fuse 6-1/4A

Product Description

The COOPER BUSSMANN BP/S-6-1/4 is a 6-1/4 amp Type S plug fuse with time-delay (Fusetron) action, sold in a 5-pack carded format. Type S fuses feature a tamper-resistant, non-interchangeable base design that prevents replacement with a higher-rated fuse — a critical safety characteristic in residential branch-circuit and appliance applications. The time-delay element allows harmless inrush currents from motors and transformers to pass without nuisance opening, while still responding quickly to sustained overloads and short-circuit faults. Licensed electricians and qualified service technicians install these as code-compliant overcurrent protection in older residential panels and appliance circuits.

Type S plug fuses are used in residential fuse panels and appliance circuits where Edison-base fuses have been rejected out or where tamper-resistant overcurrent protection is required by code. The 6-1/4 amp rating suits low-current branch circuits and small motor loads. These fuses are packaged on a retail-style card in a quantity of 5, making them a practical service-call supply item for electricians working residential service and maintenance accounts.

Key Features

• 6-1/4 amp rating with time-delay action for motor and transformer inrush tolerance
• Type S non-interchangeable base prevents substitution with a higher-amperage fuse
• Fusetron time-delay element reduces nuisance trips on startup surges
• Carded 5-pack format convenient for field stock and service calls
• Designed as a tamper-resistant replacement for standard Edison-base plug fuses

Compatibility

Designed for use in residential fuse panels and appliance circuits requiring Type S plug fuse overcurrent protection with a non-interchangeable, tamper-resistant base.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements. Always de-energize the panel and verify the circuit is dead before removing or installing a fuse. Type S fuses require a matching Type S adapter already installed in the Edison-base socket — do not force or modify the adapter. Never replace a blown fuse without first identifying and correcting the cause of the overcurrent condition.
