Amrest Electricals Ltd., a trusted name in the power industry, offers high-performance Low Voltage (LV) Monoblock Units engineered for reliable power distribution in industrial and commercial applications. Our LV Monoblock is a compact, factory-assembled system that integrates switching, protection, control, and monitoring in one robust enclosure, ensuring efficient and safe electrical management.
An LV monoblock is a pre-assembled, low-voltage terminal block or busbar system that’s used on the low-voltage side of a power transformer. It provides a safe and efficient connection between the transformer and outgoing low-voltage circuits, like power panels, switchgear, or main distribution boards.
An LV monoblock is used on the Low Voltage (LV) side of a transformer to:
Distribute power safely and efficiently from the transformer’s secondary terminals to multiple outgoing feeders.
Provide mechanical and electrical protection using an epoxy-encapsulated or resin-cast design, especially in harsh environments.
Reduce installation time and improve system compactness by replacing manually installed busbars or cables.
Improve insulation and minimize phase-to-phase or phase-to-earth faults.
Increase safety — many are touch-proof and prevent arc flash risks.
They’re especially useful in compact substations, industrial panels, and distribution transformers in both indoor and outdoor setups.
The epoxy resin is used for insulation and protection, and here’s why:
Dielectric Strength: Epoxy provides excellent electrical insulation, even at high voltages.
Environmental Protection: It seals the monoblock from dust, moisture, and pollution (especially important outdoors or in coastal areas).
Mechanical Integrity: Epoxy holds the copper or aluminum bars securely, preventing movement due to thermal expansion or vibration.
Arc Resistance: Epoxy is self-extinguishing and resists electrical arcs.
Compact Design: Molded epoxy designs allow tight configurations with high safety.
LV monoblocks simplify and secure transformer LV output connections.
Copper offers better conductivity and reliability, ideal for critical systems.
Aluminum is lighter and cheaper, good for large-scale or cost-sensitive setups.
Epoxy improves safety, durability, and insulation.
