CHINT NJMC1-16/1P: Mechanical Bistable Impulse Relay

It is not a contactor, but a CHINT NJMC1 series impulse relay, a low-power consumption bistable control electrical device.

Model Explanation

NJMC1: Model code of CHINT impulse relay series

16: Rated contact capacity (16에이)

1P: 1 pole (single contact)

핵심 매개변수

Core Features

Bistable Design: The contact state is switched by pulse signal (duration 50ms~1s). No continuous power supply is needed after switching, featuring ultra-low power consumption (different from the continuous power supply of ordinary relays).

High Compatibility: Complete AC/DC coil voltage specifications, suitable for different control circuits.

Miniaturization: Compact size, suitable for dense control cabinet layout.

일반적인 응용 분야

Suitable for low-power on-off control scenarios, ~와 같은:

– Energy-saving control of lighting circuits

– Switching of small loads (예를 들어, solenoid valves, indicator lights)

– Signal-triggered on-off circuits in automation equipment

(메모: All series adopt mechanical bistable design, triggered only by pulse signal, no continuous power supply required after switching, low power consumption and energy saving)

Key Selection Instructions (Essential for Sales/Quotation Scenarios)

1. Core Selection Dimensions:

– Number of Poles (1P~4P): Select according to the number of control circuits (예를 들어, 1P for single-circuit lighting, 3P for three-phase equipment);

– 정격전류 (10A/16A/20A/25A): Load current ≤ 80% of rated current (예를 들어, it is recommended that the load of 16A model ≤ 12.8A);

– 코일 전압: Must match the customer’s control circuit voltage (AC 220V and DC 24V are the most commonly used specifications, which can be recommended first in quotation).

2. Load Compatibility:

– Suitable for resistive loads (조명, resistance furnaces) and low-power inductive loads (small solenoid valves, fans). For capacitive loads, derating by 50% 필수.

3. Quotation and Supply Tips:

– Regular coil voltages (AC220V, DC24V) are in sufficient stock, while special voltages (예를 들어, AC12V, DC6V) need to be stocked 3~5 days in advance;

– Tiered prices are available for bulk purchases (≥ 100 units). Neutral packaging or CHINT original packaging is supported for export orders (to be specified in advance).
