A4BY3500 | Mersen 3500A Class L Time-Delay Fuse, 600V Bolt-On, 200kAIC

Mersen / Ferraz Shawmut · Circuit Breakers & Protection

Description  The Mersen A4BY3500 is a Class L, low voltage current-limiting fuse engineered for high-amperage industrial protection. It features a robust 3500 Amp rating at 600VAC/300VDC with a high interrupting rating of 200kA at 600VAC. The primary application for this bolt-on fuse is the protection of service entrance equipment, main feeders, and large circuit breakers in commercial and industrial power distribution systems.     Technical Specifications    Condition New/Never Used Surplus Brand Eaton Category Circuit Breakers Part Number QBHGF1030 Subcategory Molded Case Circuit Breakers (MCCB) Amperage Rating 30 A Voltage Rating 120VAC Poles 1 Phase 1 Interrupting Rating 22kAIC @ 120V Circuit Breaker Type GFCI (Ground Fault Circuit Interrupter) Protection Type Thermal Magnetic Trip Functions Long Time and Instantaneous Frame Type BAB Connection Type Bolt-On Terminal Connection Load Side Lug Wire Gauge Compatibility 14 to 8 AWG Standards UL, UL 943, HACR Rated Temperature Rating 40°C Weight 1.0 lbs       Information About A4BY3500 The A4BY3500 is a foundational component of Mersen’s Amp-Trap® A4BY series, renowned for its superior protection capabilities in heavy-duty applications.2 Its build utilizes a glass-melamine laminate body, ensuring high mechanical and dielectric strength under fault conditions. The fuse is compatible with standard Class L bolt-on mountings, making it a reliable solution for installation in load centers, switchboards, and panelboards. Utilizing a time-delay characteristic with a 4-second minimum delay at 500% rating, this technology allows the fuse to safely pass temporary current surges without nuisance tripping, ensuring excellent coordination with ground fault relays. Key Features: High Current Rating: Supports continuous operation up to 3500 A for heavy-duty power circuits. Voltage Rating: Operates at 600 VAC and 300 VDC for broad application flexibility. Interrupting Capacity: Rated 200 kA AC and 100 kA DC for exceptional short-circuit protection. Time-Delay Design: 4-second minimum delay at 500% load prevents nuisance fuse openings. Robust Construction: Glass-melamine laminate body ensures superior heat resistance and durability. Terminal Type: Bolt-on silver-plated copper blades provide reliable electrical contact. Standards Compliance: UL, CSA, and CE approved for safety and global compatibility. Application Range: Suitable for mains, feeders, switchboards, and large distribution panels. The A4BY3500 delivers the reliability and precision required for demanding industrial and commercial power protection systems.
