Price of popular photoprotection switches for Pakistan photovoltaic power plants
Photoprotection switches for solar PV systems in Pakistan range from PKR 1,450 for small residential DC isolators to PKR 14,500+ for industrial-grade 4-pole isolators, with MCCBs priced according to current and voltage ratings.DC Isolator SwitchesDC isolators are mandatory safety devices on the DC side of PV installations, allowing safe maintenance without disconnecting AC mains. Prices in Pakistan (2026) vary by current and voltage rating :2P 32A 1000V (residential 1–5 kW): PKR 1,8002P 63A 1000V (5–15 kW hybrid): PKR 2,8004P 100A 1000V (commercial 30 kW): PKR 5,5004P 250A 1500V (industrial PV): PKR 12,500Basic 2-pole 16A 600V panel-mount isolator: PKR 1,4504-pole 125A 1500V rooftop combiner-mount isolator with IP66 enclosure: PKR 14,500+ All switches comply with IEC 60947-3, are load-break capable, and lockable for LOTO safety .Molded Case Circuit Breakers (MCCBs)MCCBs provide overload and short-circuit protection for PV systems. Popular options in Pakistan include :2P 250A DC MCCB, 1000V: High breaking capacity of 35kA, suitable for large battery banks and industrial PV arrays.2P 200A DC MCCB: Can handle continuous loads up to 250A, with peak fault current protection up to 22kA–35kA. These MCCBs are user-friendly, reliable, and widely available from suppliers like Reliable Electric and Tomzn.pk.Industrial Load-Break SwitchesFor larger PV installations, SIRCO MC PV and GD series switch disconnectors provide true DC load-break capability, compact modular design, and remote or manual disconnection for safety and maintenance . Prices vary depending on manufacturer, current rating, and configuration, typically higher than standard DC isolators due to industrial-grade specifications.SummaryResidential PV systems: DC isolators 1,450–2,800 PKRCommercial PV systems: DC isolators 5,500 PKR, MCCBs 200–250AIndustrial PV systems: DC isolators 12,500–14,500+ PKR, MCCBs 250A 1000V with 35kA breaking capacity These switches are essential for safety and compliance in PV installations, and prices reflect current 2026 market rates in Pakistan .
