The AURORE RLT 63A Cut Out Unit C/W Fuse (Model: RC-102) is a commercial-grade electrical protection device designed for single-phase residential and light commercial power distribution across Malaysia. Rated for up to 250V AC and a maximum current of 60A/63A, this heavy-duty service cut-out unit combines a switch carrier and high-rupturing capacity (HRC) fuse protection in a flame-retardant housing. It prevents electrical overloads, mitigates short-circuit hazards, and allows quick manual circuit isolation during maintenance or emergency grid disconnections.

Performance & Safety Features

• Dual Functionality (Switch & Fuse Protection): Acts as a primary overcurrent disconnect unit while offering visual and mechanical physical isolation for electrician safety.
• High Thermal Resistance: Fabricated from thermosetting plastic compound engineered to withstand continuous operating temperatures without thermal deformation under full 63A load.
• Corrosion-Resistant Hardware: Internal connection points are fitted with anti-corrosive brass contacts, ensuring minimal resistance, zero voltage drops, and reduced localized heating.
• Tamper-Evident Enclosure Design: Built to meet standardized utility requirements for metering panels, allowing security tags or lead seals to be affixed where mandatory.
• Easy Fuse Replacement: Features an ergonomic, removable fuse carrier handle that enables safe, effortless fuse swaps without direct contact with live busbars.

Target Applications in Malaysia

1. Residential Metering Panels: Serves as the primary incoming service cut-out fuse unit installed adjacent to kWh energy meters in landed houses, apartments, and condominiums.
2. Commercial Distribution Boards (DB): Protects sub-main feeders, sub-panels, and HVAC control boxes in shoplots, office units, and retail spaces.
3. Industrial Auxiliary Machinery: Used as a localized isolator unit for high-draw single-phase equipment, motors, and commercial water heating installations.

Installation Guidelines & Maintenance

The AURORE RLT RC-102 must be installed by a registered Suruhanjaya Tenaga (Energy Commission) competent electrician. Cabling should be stripped cleanly and torqued down securely into the brass terminal blocks to prevent loose connections. Periodic inspections should check for tight terminal screws, firm fuse carrier seating, and clean contact surfaces to maintain optimal conductivity and maximum system lifespan.
 

Q1: What is the primary purpose of the AURORE RLT 63A Cut Out Unit RC-102?
A:The AURORE RLT RC-102 cut out unit protects electrical circuits from overloads and short circuits while serving as a manual disconnect switch for single-phase distribution panels.

Q2: What is the maximum current rating for the RLT RC-102 cut out unit?
A:The RLT RC-102 cut out unit supports a continuous rated current of up to 63A (60A MAX operating load) at 250V AC.

Q3: What standard fuse size is compatible with the RLT RC-102 cutout body?
A: The RLT RC-102 is designed to house standard 22mm x 58mm industrial cylindrical cutout fuse cartridges.

Q4: Is the RLT 63A cut out unit suitable for residential TNB meter panels in Malaysia?
A: Yes, 63A cut out units are widely used in single-phase residential electricity meter panels and distribution boards across Malaysia.

Q5: What material is used for the housing of the AURORE RLT RC-102 cut out unit?
A: It is constructed from high-grade, heat-resistant Bakelite material to prevent electrical tracking and withstand high operating temperatures.

Q6: Can I replace a 30A cut out fuse unit with a 63A RLT RC-102 unit?
A: Upgrading to a 63A unit depends on your incoming cable gauge and total connected load. Upgrades must be verified and performed by a licensed electrician.

Q7: How do you replace the fuse inside an AURORE RLT 63A cut out unit?
A: Turn off the main circuit, pull out the removable front fuse carrier handle, inspect or replace the internal 22x58mm 63A cartridge fuse, and push the carrier firmly back into the base unit.

Q8: Where is the RLT RC-102 cut out unit typically mounted?
A: It is surface-mounted inside or directly beside the main electricity meter box, DB board trunking, or incoming service line entrance.
