Supply Zhejiang ZSGQ-100 three-phase four-wire automatic over-voltage protection 32A40A50A63A ..

1. Scope 1.1 江智森 Zhejiang Electric Co., Ltd. Based on the current situation of the electricity developed a new generation of family home circuit protection devices. 1.11 products are small, automatic reset control circuit uses low-power high-speed micro-processor core, magnetic relays the main circuit, using circuit theory and electronic modular standards, excellent performance and reliability. For AC 380V, frequency 50Hz, rated current up to 120 amps and below the single-phase circuit. 1.12 mainly due to the grid failure caused the situation voltage instability, resulting in the emergence of high and low voltage (neutral line wrong connection, disconnection, short circuit voltage phase failure, load imbalance caused by an increase or decrease) protection, to prevent excessive or undervoltage cause damage to household appliances. 1.13 When the mains voltage is restored WIN series of automatic resettable phase over-voltage protection can automatically power, restore normal power supply, all of the normal power supply is capable of protecting the entire process automatic response, no personnel to operate. To keep people safe use of electricity and save human operation time of the operation. 1.14 panel indicator lights on the protection of working state, when the light is red disconnect protection to cut off the power, the light is green mark protection thus pull power transmission normal. Compact 1.15 product structure, beautiful appearance, installation and small circuit breaker DZ47 common rail 35mm. 2. normal environmental conditions 2.1 Ambient temperature: -20 ℃ ~ 68 ℃, the 24h average does not exceed 45 ℃; 2.11 relative humidity: ≤50% (20 ± 2 ℃) 2.12 Altitude: ≤2500m 2.13 Pollution degree: Ⅲ 2.14 normal voltage range: 0.85Un-1.1Un 2.15 to avoid near explosive, flammable substances, corrosive gases and water vapor and other significant pollution of strong magnetic fields, to avoid the impact of rain and snow and strong oscillation, IP20. 3.
