Havells DP Circuit Breaker (Double Pole)

Havells SP Circuit Breaker (Single Pole): Precision Protection for Single-Phase Circuits (Seba Electric)

What is an SP (Single Pole) Circuit Breaker?

An SP Circuit Breaker is a safety device that protects one live wire (Phase/L) in single-phase electrical systems. It monitors current flow and trips instantly during:

• Overloads: When current exceeds safe limits (e.g., too many appliances on one circuit).
• Short Circuits: When live/neutral wires touch, causing dangerous current surges.

Key Differentiator: SP breakers control only the Phase wire, leaving the Neutral (N) wire untouched. This makes them ideal for low-risk residential applications.

Why Choose Havells SP Circuit Breakers?

Havells redefines circuit protection with innovation and reliability:

1. Dual Tripping Mechanism:

   • Thermal Tripping: Bimetal strip bends during sustained overloads (e.g., 1.3x rated current).
   • Magnetic Tripping: Solenoid coil trips instantly during short circuits (e.g., 5x-10x rated current).

2. Compact & Efficient Design:

   • Slim Profile (18mm width): Fits seamlessly in crowded distribution boards.
   • High Breaking Capacity (10kA): Safely interrupts severe fault currents.

3. User-Centric Features:

   • Trip-Free Mechanism: Prevents manual override during faults.
   • Clear ON/OFF Indicators: Visual status at a glance.
   • Screwless Terminals: Tool-free wiring for faster installation.

4. Uncompromising Safety:

   • IS 60898 & IEC 60898 Certified: Meets global safety standards.
   • Flame-Retardant Housing: UL94-V0 rated polycarbonate resists fire.
   • Touch-Safe Design: No exposed live parts.

5. Versatility:

   • Current Ratings: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A.
   • Breaking Capacity: 6kA, 10kA (suitable for homes/small businesses).

Seba Electric Havells SP Breaker: Key Specifications

Product Description: Engineering Excellence in Every Breaker

Havells SP Circuit Breakers at Seba Electric are precision-engineered for fail-safe performance. The heart of the breaker is its dual tripping system:

• The thermal element uses a bimetallic strip that heats and bends during overloads, tripping the breaker after a calculated delay (e.g., 1 hour at 1.3x current).
• The magnetic element uses an electromagnet that generates a magnetic field during short circuits, tripping instantly (<0.1 seconds).

Key Design Innovations:

• Arc Chute Technology: Splits and cools electrical arcs during tripping, preventing fires.
• Silver Alloy Contacts: Ensure low resistance and high durability against welding.
• Modular Snap-Fit Mounting: Installs on 35mm DIN rails without tools.

Why Havells? With 60+ years of expertise, Havells subjects every SP breaker to:

• 10,000+ electrical endurance tests.
• Temperature cycling (-40°C to +85°C).
• Humidity resistance tests (95% RH).
  At Seba Electric, we verify authenticity and performance before delivery.

Tripping Curves Explained: Choose the Right Type

Seba Electric Tip: Use Curve C for general residential circuits.

Applications: Where Havells SP Breakers Excel

• Residential:
  • Lighting circuits (LEDs, CFLs)
  • Socket outlets (TVs, chargers, fans)
  • Low-power appliances (mixers, toasters)
• Commercial:
  • Office workstations
  • Small retail stores
  • IT server racks (low-load)
• Critical Use:
  • Emergency lighting
  • Medical equipment (low-current)
  • EV charging stations (Level 1)

Installation Guide (Seba Electric Best Practices)

1. Select Correct Rating:

   • 6A-10A: Lighting circuits.
   • 16A-20A: Socket outlets.
   • 25A-32A: ACs/geysers (only if single-phase).

2. Mounting:

   • Snap onto 35mm DIN rail in the distribution board.
   • Ensure vertical orientation for proper tripping.

3. Wiring:

   • Connect Live (L) to the top terminal.
   • Connect Load to the bottom terminal.
   • Neutral wire bypasses the SP breaker.

4. Testing:

   • Turn ON → Press “TEST” button (if available) → Verify trip.
   • Manually toggle ON/OFF to check smooth operation.

SP Breaker vs. DP Breaker: Critical Differences

Seba Electric Recommendation: Use SP breakers for lighting/sockets and DP breakers for ACs/heaters to ensure complete disconnection.
