HG1 Fuse-disconnector RT20 High Rupturing Capacity Fuse With Balde Contacts 112 Specifications:Application:Series RT14 fuses with cylindrical cap are applied in distribution units with rated voltage of AC380V and rated current up to 100A for overload and short-circuit protection.Structural Features:Series RT14 fuse is composed of fuse-link and fuse holder.(1)Fuse-linksThe two ends of fuse-link are welding connected to the cylindrical cap. Near the hottest part of the fuse-element a proper amount of low melting alloy is applied making the fuse-link having lower action temperature and power dissipation. Thus the fuse-link may adapt to overload and hardly any aging occurs.(2)Fuse-holderFuse-holder is the assembly of fuse base and fuse carrier. The base is the fixed part of fuse, which is composed of electric contact parts coordinated with the fuse-link and connecting terminals. The fuse-carrier is the movable part of the fuse used to load, unload and carry the fuse-link.The fuse holder adopts the forms of screw installation, plug-in(installing rail) installation and others.orders: payment:remarks:delivery:supply:unit_price:price_terms:FOBother_price: Specifications:It was founded in the 50's as a manufacturer of low voltage electrical apparatus specializing in fuses. By concentrating on fuses over the years, the company has grown up to be a limited company mainly in the manufacture of low voltage uses, switch-fuse combination, thermal over-load relays and a complete set of switch equipment.

Characteristics Characteristics of main circuit, see Table 4. Characteristics of auxiliary circuits: Rated operational voltage:220,380V, a. C. Conventional thermal current:5A; Rated control capacity:300VA; Utilization category: AC-15; Rated limited short-circuit current:1000A. Fuse-links type RT14-20/6 or RL-15/6 are preferred to fitted as short-circuit protection device of the auxiliary switch.orders: payment:remarks:delivery:supply:unit_price:price_terms:FOBother_price: Specifications:Application:HG30 fuse-disconnector for rail installing and module structured, and with rated voltage up to A. C.400v(50Hz)and rated operating current 100A is mainly used in the lighting and motor circuits as the power source isolator and for protection from overload and short-circuits.Structural Features:1. HG30 fuse-disconnector is composed of socket, connection terminal, fuse-link, handle outer case and clamp. All live parts are installed in the outer case and will not be exposed.2. HG30 fuse-disconnector's main overall dimensions conform to the requirement of 9 modules.3. Multipolar HG30 fuse-disconnector is composed of single polar ones.orders: payment:remarks:delivery:supply:unit_price:price_terms:FOBother_price: HG30 Fuse-disconnector RT20 1 RT14 HA & HP Switch-disconnector Specifications:Application:The operation of low voltage power net requires reliability, safely and economy. RT20 low power dissipation high rupturing capacity(HRC)fuses can protect the distribution lines and cables against all damages from fault currents between low-current overload(1.6~2 times of rated current) and rated breaking capacity.This series fuses achieve full exchangeability with similar fuses in domestic and international markets.Structural Features:1. The particular design of variable section size of fuse-element and the accurate configuration of low melting alloy taking metallurgic effect in respect of position, shape and number have lowered the power dissipation and formed ideal multi-stage protection character.2. The high-strength dense alumina ceramics tubes have excellent performances of resistance against abrupt temperature change and resistance to impact.3. High purity quartz sand with comparatively high sintering temperature is used as arc extinguishing medium.4. The integral contact knife is shaped with cold heading, which has strong structure and fine electric conductivity.5. The accessories such as single-pole bases, multi-pole bases, contact covers and partition plates can satisfy different needs.orders: payment:remarks:delivery:supply:unit_price:price_terms:FOBother_price: RT14 Filled Cartridge Fuse With Cylindrical Caps Ningbo Switchgear Electric Co., Ltd
