Overview

The Mersen SAG2-1/2 Plug Fuse (SKU: SAG2-1/2) provides essential overcurrent protection for industrial and residential circuits. Manufactured by Mersen, this 2.5 Amp, 1000 Volt fuse from the SAG series is designed to safeguard equipment from damaging fault currents and overloads. It features a low melting-point temperature element for reliable interruption. This model is part of the SAG series, which offers both non-time-delay and time-delay configurations. Non-time-delay fuses are suitable for receptacle and lighting circuits, offering rapid response to short circuits. Time-delay fuses are specifically designed for motor loads, accommodating temporary inrush currents without nuisance tripping while still protecting against sustained overloads. For Canadian applications, Type "P" fuses are used for non-motor loads, and Type "D" fuses are specified for electrical heating and cyclical load circuits. Both Canadian types also utilize low melting-point temperature elements for fast fault interruption. Type "S" plug fuses within the series are time-delay and tamper-resistant, enhancing safety in environments where unauthorized fuse replacement is a concern. The precise calibration of the low melting-point element ensures that the circuit opens when current exceeds its rated capacity for a specified duration, preventing fires and equipment damage. Proper fuse selection, such as the 2.5A rating of this model, is critical and determined by load requirements and circuit ampacity. Industries including manufacturing, commercial buildings, and residential complexes benefit from the dependable performance and quality of Mersen fuses. The SAG2-1/2 is ideal for control circuits, power distribution panels, and appliance protection where accurate and reliable overcurrent protection is paramount. Mersen's commitment to electrical safety is evident in this high-performance fuse.
