特殊用途接地故障断路器(SGFCI),C类和D类

工业Shock Block® SB5000系列是一款人员保护装置,旨在满足UL 943C针对专用GFCI的要求。本标准概述了专门为工业设施设计的GFCI类装置。C类GFCI旨在用于线间电压为480 V或以下、断路电平为20 mA的三相系统,而D类GFCI则用于600 V系统。 The SB5000 includes DFT harmonic filtering, an automatic self-test feature, and is compliant to the UL 1998 Software in Programmable Components standard.

接地故障断路器(GFCI),A类

The SB5000 is available as a 208 or 240 V Class A GFCI, allowing commercial kitchens, vehicle service centers, and other non-dwelling applications to meet NEC 210.8(B) for their three-phase loads up to 100 A.

器械接地故障保护设备(EGFPD)

The SB5000 is also available with adjustable protection settings as an EGFPD. EGFPD型号可设置为在6mA以及10至100mA之间、调幅为10mA的范围内跳闸。 This offers more flexibility since GFCI and SPGFCI devices are not permitted to have an adjustable trip level.

Ratings & Models

The SB5000 is available for three-phase voltages from 208 to 600 V with a maximum full load current up to 100 A. The power system can be either solidly or high-resistance grounded, and the load must be single-phase or three-phase as long as the load does not require a neutral. The standard enclosure is IP 69K/NEMA 4X and outdoor rated, suitable for all industrial environments including high temperature washdown used in food production applications. The 32 and 60A models are also available in a hygienic stainless steel enclosure, with a 10 degree sloped top and FDA compliant silicone gasket, designed to facilitate sanitation in food processing facilities and the like.

Grounding Monitor / Interrupter (GMI)

The SB5000 also monitors the equipment grounding connection between the Shock Block and load.这是C类和D类GFCI装置的必备功能,并且是A类GFCI和EGFPD装置的推荐功能。 If the ground-return path is broken, the SB5000 will trip and provide an alarm by changing the state of the alarm contacts. This monitoring circuit requires an extra (pilot) wire between the SB5000 and the load.在负载时,控制线与终端设备相连。 The other end of the termination device is connected to the equipment ground (typically the enclosure).

常见问答

什么是UL 943C?它与UL 943有什么区别?

UL Standard 943 applies to Class A, single- and three-phase, Ground-Fault Circuit Interrupters (GFCI) intended for protection of personnel, for use only in grounded neutral systems in accordance with the National Electrical Code (NEC®), ANSI/NFPA 70, and the Canadian Electrical Code, C22.1 (CEC), These devices are intended for use on alternating current (AC) circuits

UL GFCI类别有哪些?

A类 - 在接地故障电流为6 mA或更高(但不是4 mA或更低)时将负载电路中断的GFCI,用于线对线电压为240 V或以下的电路。B类 - 当接地故障电流超过20 mA时将负载电路中断的GFCI。 Only used with

What does the Shock Block do?

The Shock Block detects leakage current and interrupts the circuit significantly reducing or eliminating the shock potential. One key part of the additional safety features mentioned earlier, is that the Shock Block also monitors the ground wire from the unit to the load for continuity. If the wire is broken or becomes loose, the Shock Block will signal an alarm and
