Xiamen SET Electronics Co., Ltd.

Din-rail Surge Protective Device

Surge protective devices (SPDs) are designed to meet requirements for UL 1449 Forth Edition and IEC/EN 61643-21. They are DIN-rail mountable featuring a fail-safe protection, visual indicator and remote signal contact. It has a good environmental adaptability and meets the requirements of high reliability in important field.

U_c

Maximum Continuous Operating Voltage

Maximum voltage (d.c. or r.m.s.) which may be continuously applied to the SPD's mode of protection.

— (IEC 61643-21)

8/20 μs

8/20 Current Impulse

Current impulse with a nominal virtual front time of 8 µs and a nominal time to half-value of 20 µs.

I_n

Nominal Discharge Current

Crest value of the current through the SPD having a current waveshape of 8/20 µs.

— (IEC 61643-21)

I_L

Rated Current

Maximum current a current-limiting SPD can conduct continuously with no change in the impedance of the current- limiting components

— (IEC 61643-21)

U_p

Voltage Protection Level

Maximum voltage to be expected at the SPD terminals due to an impulse stress with defined voltage steepness and an impulse stress with a discharge current with given amplitude and waveshape.

— (IEC 61643-21)

Degrees of Protection Provided by Enclosure (IP Code)

Classification preceded by the symbol IP indicating the extent of protection provided by an enclosure against access to hazardous parts, against ingress of solid foreign objects and possibly harmful ingress of water.

Usage

1. Frequency range is from 47 Hz to 63 Hz.

2. The voltage applied continuously to the SPD must not exceed its maximum continuous operatig voltage U_c.

3. When atmosphere press is from 80 kPa to 106 kPa, the related altitude shall be from 2000 m to - 500 m.

4. Do not touch the product body or wires directly when power is on, to avoid electric shock.

Replacement

As SPD is a non-repairable product, for safety sake, please use the same type of SPD for replacement.

Storage

Do not store SPD at high temperature, high humidity or corrosive gas environment, to avoid oxidation of the wires. Use them up within 1 year after receiving the goods.

Installation

1. Be care of electric shock.

2. Please remove all electrical power before installation or service.

3. Keep wires as straight as possible.

4. Ensure electrical connections and mountings are correct before energizing the circuit.

5. Installation and service must be performed by qualified personnel.

6. Please install proper circuit breaker in front of SPD.

7. Do not apply mechanical stress to the SPD body during or after the installation.

Installation Position

Do not install SPD to the place that may suffer severe vibration.
