FWH-150A

The FWH-150A fuse was designed to protect smaller switching applications such as starters, relays and solenoids. It is a component of many electrical apparatus, machines, controllers, and circuit breaker systems. This type of fuse provides a fast, sure and dependable protection in applications with low voltage and current loads.

The FWH-150A is a single pole one-phase fuse, meaning it can accept a single incoming wire from the power source. The fuse is glass-enclosed and has a built-in adjustable trip mechanism, which can be set to trip at different voltages. The voltage setting can be adjusted to detect more or less current on the line. The fuse’s time-delay feature can also be adjusted, allowing it to trip quicker or slower depending on the level of current. This adjustable time-delay feature helps reduce nuisance trips.

The FWH-150A fuse also features an open fuse indication, which lets users quickly determine if the fuse is open or closed. It also has a visible melting element, which helps give users some preliminary indication when the fuse is about to trip.

The FWH-150A fuse is designed to provide reliable and fast overcurrent protection in applications with low voltage and current loads. It is UL recognized and CSA certified and meets a variety of safety and environmental standards. The fuse has a minimum operating temperature of -30°C and a maximum operating temperature of 85°C, and is safe for use in damp locations.

Working Principle

The FWH-150A fuse works by using a mechanically adjustable time delay. This time delay is triggered when the current through the fuse surpasses the preset value for a certain length of time, causing the contacts of the fuse to open, disconnecting the power supply. The adjustable time-delay feature of this fuse is particularly effective in applications that have potentially high inrush currents at start-up.

The FWH-150A fuse has an instantaneous trip mechanism, which will trip if it detects any high currents or short-circuits. This mechanism helps protect against overheating and helps ensure the safety of the equipment.

The FWH-150A fuse does not require an external power source for operation, making it ideal for use in remote locations. It is also designed to be tamperproof, so it can be used in areas where there is the potential for unauthorized access.

The FWH-150A fuse can provide reliable and fast overcurrent protection in applications with low voltage and current loads. It is UL recognized and CSA certified, making it a safe and reliable choice for many electrical apparatus, machines, controllers, and circuit breaker systems.
