Eaton 英国規格ヒューズ, 定格電流 20A, 660V ac

The Red Spot range of offset slotted fuses (or bolted tag fuses) from Eaton Bussmann is specifically designed for the protection of general industrial applications such as power distribution, cable protection and motor protection. Available in BS88 British Standard fuse sizes from A1 to A4, offset slotted and bolted fuses are suitable for general purpose rating (gG) and dual motor rating (gM) motor protection types.

• 2 to 200 A rated current
• Breaking capacity 80 kA up to 690 V ac
• Type A1 rated up to 550 V ac/ 250 V dc
• Type A2 rated up to 660 V ac / 460 V dc
• General purpose (gG) and dual motor rated (gM) types
• Low power dissipation
• ASTA 20 certified

As the fuse allows for the starting surge of a motor its full load current must not exceed the lesser of the dual current rating. e.g. 20 M25 must not have a continuous load of greater than 20A.

Use this general-purpose fuse from Eaton's Red Spot range to protect machinery from the effects of short circuits and overcurrents. It can withstand a reasonably higher current than its rating without rupturing or breaking, so it's suitable for electrical systems that experience short, harmless bursts of energy.
The fuse comes equipped with offset brackets so it can be attached to a fuse holder. This provides insulation and protects operators and equipment from electric shocks.

• High temperature tolerance prevents fuse element from exploding or arcing in the event of overcurrent
• High rupture capacity (HRC) for long-term use
• T speed for tolerance to short energy spikes
• Low power loss for improved energy efficiency

An overcurrent is a condition where the supply current to a circuit is higher than its normal operating current. This could be due to an overload or a short circuit.

To ensure it works properly and safely, a fuse's current rating must be above the normal operating current of the circuit, so it's important to check compatibility before you install your fuse.
