3BHE030410R3011 PPD117A3011 entry-to-mid-range Power Protection & Detection Module

3BHE030410R3011 PPD117A3011 is a cost-effective, entry-to-mid-range Power Protection & Detection Module developed by ABB, specifically designed for low-to-medium voltage (0.4kV–6.6kV) small-to-medium power electronic systems (0.5MW–5MW). It serves as a "basic safety guard" for equipment such as small industrial drives, low-power renewable energy converters (e.g., rooftop solar inverters, small wind turbines), and auxiliary power systems in factories. By integrating core fault detection functions, simplified insulation monitoring, and easy integration with ABB’s entry-level control units (e.g., PPC380AE, ACS380 drives), it prioritizes usability, cost-effectiveness, and reliable protection for low-to-medium power scenarios, focusing on safeguarding common power semiconductors (low-voltage IGBTs) and avoiding unplanned downtime. The detailed information is as follows:

1. Basic Product Overview

Category	Details
Manufacturer	ABB (a global leader in industrial automation and power technologies, adhering to international standards such as IEC 61800-5-2 (power drive safety), IEC 60255-1 (general relay requirements), and IEC 61000-6-2 (industrial EMC immunity). It is widely trusted in small-to-medium industrial, commercial, and renewable energy sectors.)
Product Type	Low-to-Medium Voltage (0.4kV–6.6kV) Power Protection & Detection Module (dedicated to overcurrent/overvoltage/undervoltage detection, basic insulation monitoring, and fault signal output for 0.5MW–5MW power conversion systems)
Model & Order Number	- Product Model: PPD117A3011 - Order Number: 3BHE030410R3011 (unique identifier for procurement, inventory management, after-sales service, and compatibility verification with ABB’s entry-to-mid-range product ecosystem)
Package Type	Compact panel-mounted/rack-mounted enclosure (19-inch rack-compatible, 1U height optional; plastic-metal hybrid housing with IP20 dust-proof protection; front-panel 2-line LCD display + 3 LED indicators for status monitoring: power (green), normal (steady green), fault (red flashing))
Weight	Approximately 0.8–1.2 kg (varies by accessory kits, including mounting brackets, common-specification wiring terminals, a quick-start guide, and basic calibration tools)
Key Compatibility	Optimized for ABB’s entry-to-mid-range product lines, including ACS580 series medium-voltage drives (0.5MW–5MW), PCS100 series small renewable energy converters (0.1MW–2MW), and auxiliary power supplies for factories. It integrates seamlessly with ABB’s PPC380AE control units or standalone low-voltage drives via hard-wired signals or basic Modbus communication.

2. Key Electrical & Hardware Specifications

2.1 Power Supply & Basic Reliability

Input Voltage: Single 24VDC ±10% (supports parallel redundant power supply for critical small systems; no hot-swap function, but low power demand simplifies backup design).
Power Consumption: Typical 5W (normal monitoring state), maximum 10W (fault detection and signal transmission active) – suitable for small auxiliary power loops.
Isolation Performance:
- Between power input terminals and signal terminals: ≥1500V AC (1 minute, IEC 60664-1 standard) – prevents low-voltage control circuit interference from affecting detection stability.
- Between current sampling terminals (CT input) and low-voltage control terminals: ≥2000V AC (1 minute) – ensures operator safety during wiring and maintenance.

2.2 Detection Capabilities & Parameters

2.2.1 Core Current & Voltage Detection

Overcurrent/Short-Circuit Detection:
- Input signal type: AC current (via small-to-medium size industrial CTs with ratio 50:5A, 100:5A, 200:5A – compatible with 0.5MW–5MW system current specifications);
- Detection range: 0–200A (continuous current), 0–1000A (peak surge current);
- Accuracy: ±3% (within 20%–100% of full scale) – meets the protection precision needs of entry-to-mid-range systems;
- Response time: ≤100μs (for short-circuit current exceeding 200% of rated value) – fast enough to protect low-voltage IGBTs from thermal damage.
Overvoltage/Undervoltage Detection:
- Input signal type: AC grid voltage (direct sampling for 0.4kV–1kV systems; via low-voltage VTs with ratio 6.6kV/100V for 6.6kV systems);
- Detection range (AC): 0–8kV (rms);
- Configurable thresholds (via dip switch or local buttons):
  - Overvoltage: 110%–120% of rated voltage (e.g., 440V–480V for 400V systems);
  - Undervoltage: 80%–90% of rated voltage (e.g., 320V–360V for 400V systems).

2.2.2 Basic Insulation & Temperature Monitoring

Insulation Resistance Monitoring:
- Monitoring range: 0–1000MΩ (for power module and DC bus insulation to ground);
- Testing method: Passive insulation measurement (avoids interfering with system operation, simple and reliable);
- Fixed alarm threshold: 50MΩ (suitable for low-to-medium voltage small systems);
- Testing frequency: 1 time/5 seconds (balances monitoring timeliness and power consumption).
Temperature Monitoring:
- Input channels: 2 channels (for connecting NTC thermistors on IGBT heatsinks and cabinet air inlets);
- Detection range: -20°C to +120°C;
- Fixed thresholds: Warning (80°C), trip (95°C) – matches the thermal limits of low-voltage IGBTs in small drives.
