The SCHURTER 40A Glass Tube Fuse C3158373 provides reliable overcurrent protection for AC circuits up to 250V with a 4A continuous current rating. Its glass tube construction and wide operating temperature range (-55°C to +125°C) make it suitable for industrial, automotive, and renewable energy applications. Critical parameters include interrupt rating (40A), voltage (250V AC), and current (4A), with soldering requiring high-temperature techniques. Designers should ensure proper thermal management and verify AC compatibility. Market strengths include ROHS compliance and compact size, while limitations involve voltage specificity and packaging minimums.
