HAGERS APTIS
HAGERS, being a prominent electrical product manufacturer, offers various distribution board (DB) solutions, and the terms SPN DB, TPN DB, and One-Way Enclosure refer to specific characteristics of these boards. Here’s a breakdown for better understanding:
Description
1. HAGERS SPN DB (Single Phase + Neutral Distribution Board):
- Function: Designed to manage and distribute single-phase electrical power. This means it handles one “live” wire (phase) and a neutral wire for the return circuit.
- Application: Commonly used in residential and commercial buildings where single-phase power is sufficient for most appliances and lighting.
2. HAGERS TPN DB (Three Phase + Neutral Distribution Board):
- Function: Built to manage and distribute three-phase electrical power. This provides three “live” wires (phases) offering higher power capacity compared to single-phase systems.
- Application: Primarily used in industrial settings and large commercial buildings requiring high power for machinery and equipment.
3. One-Way Enclosure:
- Function: Refers to the physical design of the distribution board, not its electrical configuration. It simply indicates that the enclosure features one door on the front for accessing the internal components like circuit breakers and wiring.
- Application: One-way enclosures are commonly used in both SPN and TPN DBs, depending on the manufacturer’s design and available options.
In summary:
- SPN DB and TPN DB differentiate based on the type of electrical power they handle (single-phase or three-phase).
- One-way enclosure describes the physical design of the board, not its electrical configuration.

HAGERS Indicating Lights
HAGERS Indicating Lights are visual signaling devices designed to provide information about the status of an electrical circuit or system. They offer a quick and easy way to:
- Monitor the operational state: Indicate whether a circuit is energized (on) or de-energized (off).
- Identify potential problems: Signal potential issues within a system, such as faults or overloads.
- Enhance safety: Provide a visual confirmation of system status, aiding in safe operation and maintenance procedures.
