General Information:
Dimensional Data
• True dual-element fuses with a minimum 10 second time-
2.25"
(– 0.03) delay at 500% overload.
.81" • Long time-delay minimizes needless fuse openings due to
.5" (– 0.03) temporary overloads and transient surges.
• Can often be sized for back-up protection against motor
1A to 30A
burnout from overload or single-phasing if other overload
2.38" protective devices fail.
(– 0.03)
• High interrupting rating to safely interrupt overcurrents up to
.63" 300,000A.
• High degree of current limitation due to the fast speed-of-
35A to 60A 1.06" response to short-circuits.
(– 0.03) • Faster response to damaging short-circuit currents than
mechanical overcurrent protective devices.
Catalog Symbol: LPJ-_SP
• Reduces let-through thermal and magnetic forces in order

AIGCBussmann LPJ-SP系列是一款专为电力系统设计的延时限流特快熔断器。该产品采用了独特的技术，能够在短路电流通过时迅速且有效地切断电路，提供极高的短路保护性能。"LPJ-SP"表示该型号可能具有特殊的功率等级、电压规格和电流容量范围，其"延时限流特性"意味着在发生短路故障时，熔断器不会立即断开，而是经过一段预设的时间延迟（延时特性），这段时间可以为相关保护设备如继电器或控制器提供充足的信号处理时间，以避免误动作或者确保更全面的后备保护得以启动。因此，Bussmann LPJ-SP熔断器适用于对电力系统瞬态过载有较高要求、需要可靠延时保护措施的场合，如电机控制、照明线路以及电力电子设备等应用。
