Description

Honeywell 10310/2/1 Earth Leakage Detector

Product Overview

The Honeywell 10310/2/1 is a compact Earth Leakage Detector for DC systems. It supports 24, 48, 60, and 110 Vdc networks. The fixed fault threshold is 5.5 mA (±1 mA) with a maximum earth current of 25 mA (±5 mA). CE and UL approved.

Technical Configuration

10310/2/1 – /2 indicates 24 Vdc primary operation with 115 V support. /1 denotes a 1 A relay output.

Rst24 – Input 18...70 Vdc (1.1 mA @ 24 Vdc)

Rst110 – Input 40...130 Vdc (2.5 mA @ 110 Vdc)

Installation Guide

Set gap voltage with a precision DC source. Normal earth voltage is -12 Vdc. During fault, it shifts to -30...+125 Vdc. Use shielded twisted-pair cables with a 10x diameter bend radius. For hazardous areas, install zener barriers or isolators.

Key Advantages

  • Operating temperature -20 °C to +70 °C, 95% humidity
  • Direct interface with TSI systems via relay output
  • Fault response time under 100 ms
  • Drop-in replacement for older 3300 series ELDs

FAQs

Q1: How to test the fault threshold?

A1: Inject 0-10 mA between DC negative and earth. Relay trips at 5.5 mA ±1 mA.

Q2: Can it replace an older 10310/1/0?

A2: Yes. The /2/1 offers wider input voltage (18-70 Vdc) and higher output (1 A).

Q3: What does CE approval cover?

A3: Compliance with EMC and Low Voltage Directives, tested to IEC 61000-6-2 and IEC 61000-6-4.
