Fuse link Etipo ETI Polam BiWtz 002313412 40A gG 690V DIII time-delay

Cartridge fuse Etipo ETI Polam BiWtz model 002313412 is a time-delay (slow-blow) gG fuse with a rated current of 40 A and a voltage rating of 690 V in size DIII. It is constructed for general-purpose protection of electrical circuits, allowing short-duration inrush currents while interrupting sustained overloads and short circuits. The fuse's time-delay characteristic makes it suitable for applications where temporary current surges occur during motor starts or transformer energization.

Advantages

This time-delay gG fuse provides reliable protection against overloads and short circuits while permitting temporary inrush currents, reducing nuisance interruptions. Its cartridge design and DIII size make replacement straightforward in compatible fuse holders and fuse switches. The fuse's high voltage rating and general-purpose characteristic offer broad applicability across industrial and commercial installations where robust circuit protection is required.

Suitable for

• Protection of motor circuits and motor starters where inrush currents are expected
• Industrial and commercial electrical distribution panels
• Protection of transformers and general-purpose circuit protection in machinery

Key specifications

• Rated current: 40 A
• Time-delay characteristic (slow-blow)
• Utilization class: gG (general purpose)
• Rated voltage: up to 690 V
• Size: DIII (cartridge fuse)

How to use

Install the cartridge fuse in a compatible DIII fuse holder or fuse switch according to the electrical installation standards and the equipment manufacturer's instructions. Ensure power is isolated before replacing the fuse. Select the fuse for the correct rated current and utilization class for the circuit to ensure coordinated protection. After replacement, verify correct seating and restore power, checking that the protected circuit operates normally without abnormal heating or repeated fuse operations.

Usage recommendations

Use this time-delay gG fuse where temporary inrush currents are present; coordinate fuse ratings with upstream and downstream protective devices to maintain selectivity. Verify compatibility with the fuse holder and observed operating conditions, and replace only with identical type and rating.
