TOMZN 3 Phase 4 Pole AC SPD TZG40-C (20KA-40KA) 420V - Advanced Surge Protection for Bangladesh

Overview

In today's electrically sensitive world, protecting valuable electronic equipment from power surges is paramount, especially in Bangladesh where power fluctuations and lightning strikes can be common. The **TOMZN 3 Phase 4 Pole AC SPD (Surge Protective Device) - TZG40-C (20KA-40KA) 420V** is engineered to provide robust and reliable protection for your critical electrical systems. This high-performance Type 2 surge protector is designed for installation at the service entrance of industrial facilities, commercial buildings, and large residential setups, safeguarding against transient overvoltages caused by lightning, utility switching, and other electrical disturbances. The TZG40-C model boasts a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 40kA, ensuring it can effectively divert significant surge energy away from your sensitive equipment. With a maximum continuous operating voltage (Uc) of 420V AC, it's perfectly suited for 230V/400V AC 3-phase electrical systems prevalent in Bangladesh. Its 4-pole configuration provides comprehensive protection for all three phases and the neutral line, offering peace of mind and extending the lifespan of your appliances and machinery.

Why Surge Protection Matters in Bangladesh

Bangladesh's power grid, while continuously improving, is still susceptible to various electrical anomalies. Lightning activity, especially during monsoon seasons, can induce massive surges that devastate unprotected electronics. Moreover, frequent load shedding and grid switching operations can generate internal surges that are equally damaging over time. Investing in a high-quality SPD like the TOMZN TZG40-C is not just a precaution; it's an essential measure to: * Prevent costly damage to industrial machinery, servers, computers, and home appliances. * Reduce downtime in businesses and critical operations. * Enhance safety by minimizing fire risks associated with electrical overloads. * Ensure the longevity and reliable performance of your entire electrical infrastructure.

Key Features

The TOMZN TZG40-C SPD is packed with features designed for superior surge protection and ease of use: * **High Discharge Capacity:** With a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 40kA (8/20µs waveform), this SPD can handle significant surge energy, making it ideal for robust protection requirements across Bangladesh. * **Optimal Operating Voltage:** A maximum continuous operating voltage (Uc) of 420V AC ensures compatibility and effective protection for 3-phase 230V/400V AC systems. * **Fast Response Time:** Boasting a response time of less than 25 nanoseconds (<25ns), the device acts almost instantaneously to divert surges, minimizing the exposure of your sensitive equipment to damaging transients. * **Low Voltage Protection Level (Up):** Achieves a voltage protection level (Up) of ≤1.8kV, meaning that once the surge is diverted, the residual voltage passed to your equipment is kept at a safe, low level. * **4-Pole Configuration:** Provides comprehensive protection for all three phases (L1, L2, L3) and the neutral line, crucial for balanced 3-phase systems. * **Modular Design:** Features a plug-in module design for easy replacement without disconnecting the entire device from the DIN rail, simplifying maintenance and reducing downtime. * **Visual Status Indicator:** Each protective module includes a clear visual indicator (Green for normal operation, Red for fault/end-of-life) for quick and easy status monitoring. * **DIN Rail Mounting:** Designed for standard 35mm DIN rail installation, ensuring straightforward integration into existing distribution boards and electrical panels in Bangladesh. * **Flame-Retardant Material:** Constructed from high-quality, flame-retardant thermoplastic (PA66, UL94 V-0 rated) for enhanced safety and durability. * **Compliance with Standards:** Manufactured in accordance with IEC/EN 61643-11 standards for Type 2 SPDs, guaranteeing reliability and performance.
